Embedded with youthful humour and charged emotions, this offbeat college campus story revolves around Kumaaran, or as students call him, Captain (Mohanlal), who was the star of Mahatma college before he joined the army. Now an ex-military officer, Kumaaran is running the canteen of Mahatma College after a tragic incident that resulted in the fatalities of his father and sister.
Kumaaran is dear to all the students and he actively engages with them, whether in youth festivals, love affairs, fights, or campus tours. He even helps them bring teachers back from their private tuition classes to the college.
Madhavi (Vimala Raman), the college's English professor, hates him because she saw Kumaaran getting involved in a fight with a street rowdy. Once during a campus tour, the bus gets involved in an accident, killing several students. Madhavi let's her pious affect her, jumps to conclusions and tells everyone that Kumaaran was the reason for the accident. Can Kumaaran prove his innocence to the world, and successfully regain the trust of his students and of Madhavi?
